We will define the environmental impact that suffers a certain region as the difference among the future environmental situation of the place, after the realization of a project, and the environmental state of the area if this project had never taken place. The correct diagnosis of the impact demands to know all the elements implied in the environmental process. A study of environmental impact will also include a planning of the environmental surveillance of the project.

One of the fundamental physical systems for the study of the environmental quality of a region is the atmosphere. The atmosphere play a fundamental paper in the development of the life. In this software, we will center ourselves in the study and in the administration of the noise pollution.

Airports are associated with air and noise pollution and may, therefore, reduce the quality of life of local people. This study assessed the link between aircraft noise and subjective wellbeing, using data from 17 English airports. The authors conclude that living under flight paths has a negative effect on people’s overall wellbeing, equivalent to around half of the effect of being a smoker for some indicators.

Software requirements in the 80`s
Until the 80`s most consultancy projects were based on noise measurements due to complaints.
As noise legislation became more strict, noise prediction became more important.
New national and international noise prediction standards
As there was no commercial software available many consultants started to develop their own prediction software
First software
No Graphical User Interface.
Manual data entry, ASCII files in/out, small models

The railway rolling noise prediction software (RRNPS) is a simulation model for predicting the sound pressure levels during a train passage due to wheel/rail roughness, based on vibration dynamics, contact mechanics and sound radiation modules. Some field validation has been done under European and Australian conditions. Comparisons between simulations and measurements have shown that this software model gives reliable predictions in terms of overall A-weighted sound pressure level and noise spectrum. In this...
